BENHAM, Justice.

On July 5, 1998, appellant Terry Franklin and Maurice Coleman severely beat the victim Kenneth Briddell who died from his injuries three months later.1 1. Appellant alleges the evidence was insufficient to convict him of felony murder. At trial, Coleman and two other witnesses testified that Coleman hit the victim with a gun and appellant stomped and kicked the victim in the head and mouth as the victim was prone on the ground. The evidence showed that, at the time of the beating, the victim owed appellant $5 in drug money. The victim was treated in the hospital for his injuries, but was in a chronic vegetative state such that he had to be surgically fitted with a tracheal tube for breathing and another tube for feeding. The treating physician stated that the victim was awake, but not alert or oriented, and that his chronic vegetative state would not improve. After three months in the hospital, the victim was set to be moved to a permanent care facility. However, on October 10, 1998, the victim's tracheal tube became dislodged such that he could not breathe and he went into respiratory arrest and then his heart stopped beating. Although life-saving measures were attempted, the victim died that day. The victim's treating physician listed the victim's cause of death as respiratory arrest and asystole. The county medical examiner later reviewed the victim's medical records and amended the death certificate to indicate that the cause of death was delayed complications of blunt head trauma. In explanation of his reasons for amending the death certificate issued by appellant's treating physician, the county medical examiner testified as follows:

On June 5, 1999, approximately eight months after the victim died, authorities arrested appellant for murder. While riding in the car on the way to be fingerprinted and booked, appellant told the arresting officer that he had "beat up dude" but that he had not hit the victim with a gun.

(a) Appellant does not dispute that he beat the victim. He contends, however, that his actions did not cause the victim's death because the treating physician listed the cause of death as respiratory arrest and asystole, conditions which were immediately triggered by the tracheal tube becoming dislodged at the hospital. We disagree.

Currier v. State, 294 Ga. 392, 394(1), 754 S.E.2d 17 (2014). Here, the dislodgement of the tracheal tube was not an unforeseen intervening cause of the victim's death because the beating placed the victim in a chronic vegetative state necessitating the placement of the tracheal tube. As such, the dislodging of the tracheal tube was only secondary to the beating which was the proximate cause of death. See Skaggs v. State, 278 Ga. 19(1), 596 S.E.2d 159 (2004) (kicking the victim with a steel-toed boot was proximate cause of the victim's death days later; the victim's fall head-first onto concrete after being kicked was not reasonably unforeseeable); Green v. State, 266 Ga. 758(2)(b), 470 S.E.2d 884 (1996) (defendant's stabbing his wife was the proximate cause of her death from a stress ulcer); Dupree v. State, 247 Ga. 470(1), 277 S.E.2d 18 (1981) (defendant's actions in robbing the victim at gunpoint and hitting the victim were the proximate cause of the victim's death by cardiac arrest). The jury was authorized to reject any alternate theory of causation and conclude that appellant's actions in beating the victim caused the victim's death. Neal v. State, 290 Ga. 563(1), 722 S.E.2d 765 (2012). See also Bryant v. State, 270 Ga. 266(1)(a), 507 S.E.2d 451 (1998) (evidence sufficient to convict on charge of felony murder where gunshot to the head caused victim to be immobilized for a significant amount of time during treatment and recovery; said immobilization put the victim at greater risk of suffering the pulmonary embolism that caused her death). Accordingly, the evidence was sufficient for a rational jury to find appellant guilty beyond a reasonable doubt of the charge for which he was convicted. Jackson v. Virginia, 443 U.S. 307, 319, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979).

(b) Appellant alleges that the medical examiner was not authorized to investigate the victim's death and/or amend the death certificate under OCGA §§ 31-10-6 and 45-16-24. Our review of the record shows appellant failed to make any objection at trial to the evidence regarding the medical examiner's investigation of the victim's death or to the amended death certificate. Accordingly, this issue has not been preserved for appellate review. See Matthews v. State, 294 Ga. 50(2), 751 S.E.2d 78 (2013); Hall v. State, 292 Ga. 701(2), 743 S.E.2d 6 (2013). See also Crawford v. State, 267 Ga. 543(6), 480 S.E.2d 573 (1997) (defendant could not raise grounds on appeal that were not raised below challenging the admission of the deceased's death certificate).

2. Appellant alleges he is entitled to a new trial because the trial court failed to remove Juror 13 for cause. We disagree. An appellate court pays deference to the trial court's resolution of any equivocations or conflicts in a prospective juror's responses. Lewis v. State, 279 Ga. 756(3)(a), 620 S.E.2d 778 (2005). The determination of a potential juror's impartiality is within the trial court's sound discretion and the trial court will only be reversed on such matter upon finding a manifest abuse of discretion. See Kim v. Walls, 275 Ga. 177, 178, 563 S.E.2d 847 (2002). See also Poole v. State, 291 Ga. 848(3), 734 S.E.2d 1 (2012). Here, Juror 13 raised his hand when the trial court asked, on behalf of the prosecution and the defense, the following question: "Do any of you believe that it is the job of the defense attorneys to trick you?" Appellant did not ask any follow-up questions regarding Juror 13's response to the question and the only discussion regarding Juror 13's potential service was whether he had a valid hardship that would preclude his service. When defense counsel mentioned that she might want to remove Juror 13 for cause, the trial court noted she had failed to ask any follow-up questions during the individual voir dire and he allowed Juror 13 to remain in the jury pool. Appellant then used one of his peremptory challenges to strike Juror 13. In this case, there has been no showing that the trial court manifestly abused its discretion and so this alleged enumeration of error cannot be sustained. Id.

3. Appellant alleges the facts of the case did not conform to the jury charges given by the trial court so as to authorize the jury to find him guilty of felony murder. The trial court charged in pertinent part regarding the connection between the felony and the homicide:

After the jury retired to the jury room, appellant complained that the judge instructed that the felony had to have a "logical relationship" to the homicide rather than a "legal relationship" to the homicide. Accordingly, the trial court gave the jury the following recharge:

Appellant voiced no further objection to the charges or the recharge, reserving any other objections to the jury charges for a later time.

In his brief, appellant argues that under the trial court's recharge, his conviction cannot stand because there was no showing that the homicide occurred before or during the "full execution" of the aggravated assault. This argument has no merit. On appeal, we read the jury charges as a whole to determine the presence of any error. Sapp v. State, 290 Ga. 247, 251(2), 719 S.E.2d 434 (2011). In this case, the jury charges, including the initial charge and the recharge, are correct statements of the law. See id. (where trial court gave same pattern charge regarding the felony's relationship to the homicide as was given in the case at bar); Suggested Pattern Jury Instructions, Vol. II: Criminal Case, § 2.10.30 (4th ed.2007, updated through July 2013). Contrary to appellant's argument, the jury was not required to find that the homicide occurred prior to or during the completion of the felony aggravated assault. Both the original charge and the recharge stated that the homicide and felony needed only to be concurrent "in part" and that the homicide occur before any attempt by appellant to avoid conviction or arrest. The evidence shows that the head trauma, complications from which led to the victim's death, was received during appellant's aggravated assault of the victim by beating and kicking the victim in the head and that the death of the victim occurred prior to any attempt by appellant to avoid conviction or arrest. Therefore, the jury charges and the facts of the case were in conformity and, as discussed in Division 1, supra, the evidence was sufficient for appellant to be convicted of felony murder.

Judgment affirmed.

All the Justices concur.
